Interior Lamps
Instrument Panel Brightness Control
This feature controls the instrument panel lights.
The control for this feature is located on the exterior
lamps control. Your parking lamps must be on for this
feature to work. Turn the control clockwise to brighten
the lights or counterclockwise to dim them.
Courtesy Lamps
When any door is opened, several lamps come on. These
lamps are courtesy lamps. They make it easy for you to
enter and leave your vehicle. You can also turn these
lamps on by turning the exterior lamps control all the
way clockwise.
Some of the lamps have switches so you can turn them
on, even when the doors are closed. These lamps are
reading lamps.
Illuminated Entry (If Equipped)
Your courtesy lamps will come on and stay on for a set
time whenever you press UNLOCK on the remote
keyless entry transmitter (if equipped).
If you open a door, the lamps will stay on while it's open
and then turn off automatically about 25 seconds after
you close it. If you press UNLOCK and don't open a
door, the lamps will turn off after about 40 seconds.
Illuminated entry includes a feature called theater
dimming. With theater dimming, the lamps don't just
turn off at the end of the delay time. Instead, they slowly
dim after the delay time until they go out. The delay
time is canceled if you turn the ignition key to ON or
press the power door lock switch. The lamps will dim
right away.
When the ignition is on, illuminated entry is inactive,
which means the courtesy lamps won't come on unless
a door is opened.

2-58 Delayed Entry Lighting
Delayed entry lighting illuminates the interior for a
period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting to
work. Immediately after all the doors have been closed,
the delayed entry lighting feature will continue to work
until one of the following occurs:

The ignition is moved to ON,

the doors are locked, or

an illumination period of 25 seconds has elapsed.
If during the illumination period a door is opened, the
timed illumination period will be canceled and the
interior lamps will remain on because a door is open.
Delayed Exit Lighting
This feature illuminates the interior for a period of time
after the key is removed from the ignition.
The ignition must be off for delayed exit lighting
to work. When the key is removed, interior
illumination will activate and remain on until
one of the following occurs:

The ignition is moved to ON,

the power door locks are activated, or

an illumination period of 25 seconds has elapsed.
If during the illumination period a door is opened, the
timed illumination period will be canceled and the
interior lamps will remain on because a door is open.

2-59
Parade Mode
The instrument panel has an added feature called parade
mode. This feature prohibits the dimming of your
instrument panel displays during the daylight while
the headlamps are on so that you'll still be able to
see the displays.
Rearview Mirror Reading Lamps
Use the switch next to each lamp to turn them
on and off.
Reading Lamps (If Equipped)
The reading lamps are located on the assist handles in
the headliner. These lamps and the interior courtesy
lamps come on when any door is opened. Press the lens
to turn them on. Press it again to turn them off.
Dome Lamp (If Equipped)
The dome lamp will come on when you open a door.
You can also turn this lamp on by turning the exterior
lamps control clockwise as far as it will go. Vehicles that
have the optional sunroof do not have a dome lamp.
Battery Rundown Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave on the
interior courtesy lamps, reading/map lamps, visor vanity
lamps, trunk lamp or glove box lamps.. If you leave any
of these lamps on, they will automatically turn off after
10 minutes, if the ignition is moved to OFF. The lamps
won't come back on again until you do the following:

Turn the ignition on, or

turn the exterior lamps control off, then on again.
If your vehicle has less than 15 miles (25 km) on the
odometer, the battery saver will turn off the lamps after
only three minutes.
Battery rundown protection will also work if the
headlamps are left on. After having been left on for
10 minutes, the headlamps and the parking lamps will
flash three times. They will remain on for one more
minute before being turned off automatically.
Mirrors
Adjust all the mirrors so you can see clearly when you
are sitting in a comfortable driving position.

ready. That can make it overheat, damaging the
lighter and the heating element.

can also move them from side to side. The visors also

driver's side of the vehicle.
While refueling, let the fuel cap hang by the tether
below the fuel fill opening.

Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly. Look for any other loose or damaged
safety belt system parts. If you see anything that might
keep a safety belt system from doing its job, have it
repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag system
does not need regular maintenance.)

inserts that appear worn or damaged or that streak or
miss areas of the windshield. Also see ªWiper Blades,

At least twice a year, check to see if the system is
working properly. Make sure the horn chirps and
